They are both so close that it makes little sense to have separate questions.

However, score 2 is pretty uninteresting.

(The rationale of this question is to find the duplicates so we can get the administrators to merge them. It is also to find better ways to find dupes in the first place, and perhaps turn finding duplicates into a game.)

Marc, this is about the search for the most rampant duplicate, which is one possible solution to the duplicate problem. its not about solving the problem, it a much narrower, and hopefully more fun question.

One that comes up again and again is floating point comparisons e.g. "why is if (myFloat == 23) not working?"

I'm pretty sure "Regular Expression Help" gets asked most often, but we always change its title to something a bit more descriptive.

Fantastic question -- at last a rep-incentive for closing dupes, and look ma no code changes! (Even if it's only meta-rep.) IMHO it should be a requirement to list all the question URLs in your answer to get upvotes here.

@George: Good answer, but in order to make this question all it can be (namely: a real life dupe-findin', rep-rewardin' machine) I'm -1ing until you give up the URLs.

Well, sometimes "don't" is the proper and professional answer... but that's a different discussion for a different time. I would have figured that was a prime target for duplicates, I just never expected that much ... variety ... in the wording.

Don't is definitely not the answer, the answer comes in regards to availability guidelines. If you only LIKE to have your site up, be all means host from home. If you NEED your site up. Use a real host.

What's scary is the same answer applies to "How to parse HTML with RegEx" - again the ideal answer is "Don't" but there are some limited cases where it's possible ;)

As of today, a search for +host +server +home turns up 1,153 results on SF. Not all of them are this question, but it appears that the vast majority are.

That looks more like a topic than a question archetype.

(* == closed; some of these are duplicates themselves, and have since been merged, some are just really persistent OT / NC)(And yes, I'm counting deleted posts too - lookin' at you, PHP)

select top 30 count(*) as dups,
concat('http://stackoverflow.com/q/', RelatedPostId) as Q,
case when q.ClosedDate is not null then '*' else '' end as Closed
from PostLinks
join Posts q on q.Id=RelatedPostId
where LinkTypeId=3
group by RelatedPostId,q.ClosedDate
order by count(*) desc

The MySQL one would have been my guess for the top-spot... they're a never-ending deluge; and those are just the ones that got closed as dupes of the merged dupes at the top... your query isn't recursive ;-).

Eric, there is no clear unambiguous list for the moderator to work with. See how Marc was able to resolve the dupe I posted in seconds. Surely you could beat my measly score of 2.

Jon kindly listed some of them here... and that was just in November; it will be longer now...

The problem with this language gotcha is that until you understand what is happening, you can't know what to look for... IMO, this is one of the good use-cases for tag-specific home pages, where we can (manually) add a FAQ for that tag (i.e. link to the canonical answer).

What also springs to mind are the countless variations on the theme "What is the best Python (web) framework?", with ever so subtle differences in emphasis and formulation. (Right now I'm not delving too deep into those, but take a look at python+frameworks, python+framework and python+web-frameworks.)

@trufa ~ My motto is that all programmers should be lazy. But not too lazy. (mainly in re: functions and reuse, etc. Copy-paste twice, but after that make a function and quit copy-pasting, too much effort to do so, making a function makes you lazier ... blah blah TL;DR ;] )

Anything where the answer is dos2unix. The symptoms are varied and the clue quotient of the OPs is mostly, shall we say, chequered. In the end, by the time it's solved, it's obviously off-topic for SO, but you see some good programming and debugging coaching in the speculations leading up to that.

The examples I am finding are less spectacular than the best I've seen. These all contain literally dos2unix in the answer, but there will be hundreds more with different wording.
